Will Cablevision pursue a wireless voice service?

It looks like another cable company is swimming in the wireless waters. During its earnings conference call, Cablevision hinted it may launch a wireless voice service. "I think that a wireless voice network riding on top of a wireless data network is inevitable," Cablevision COO Tom Rutledge said during the call. Last year, Cablevision announced plans to spend more than $300 million to roll out WiFi in New York and Long Island. It's unclear exactly how Cablevision would move forward with a voice play, though, and whether it would include a cellular component. However, Rutledge said "there is a significant opportunity there to create a voice business with very little capital expenditure." See a transcript of Cablevision's earnings call here [1].
